TOOL FOR TRlNlNl-ING HORSES HOOFS.

SPECIFICATION forming part of Letters Patent No. 427,115, dated May 6,1890.

Application filed January 13, 1890. Serial No. 336,742. (No model.)

To @ZZ whom, it mfc/'zj concern: Beit known that I, ANDREW M. ROBERTS, acitizen of the United States, residing at Mitchell, in the county ofCrook and State of Oregon,have invented certain new and usefulImprovements in Tools for Trimming Horses Hoofs; and I do declare thefollowing to be a full,clear, and eXact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

This invention relates to certain new and useful improvements in thatclass of blacksmiths tools which are used for trimming the hoofs ofhorses; and it has for its object to generally improve upon theconstruction, and at the same time render more durable and efiicient inoperation this class of devices.

To these ends and to such others as the invention may pertain the sameconsists in the peculiar construction and in the novel combination,arrangement, and adaptation of parts, all as more fully hereinafterdescribed, shown in the accompanying drawings, and then speciiicallydefined in the appended claims.

The invention is clearly illustrated. in the accompanying` drawings,which, with the letters of reference marked thereon, form a part of thisspecification, like letters of reference indicating` like partsthroughout both views, and in which drawingsp Figure 1 is a perspectiveview of a hooftrimming tool constructed in accordance with my invention.Fig. 2 is a vertical longitudinalsection of the same.

Reference now being had tO the details of the drawings by letter, A andB represent the main operating-handles. The handle A is provided at itsend with the horizontally-flattened and substantially triangular portionA2, the edges of which are beveled, so as to form the cutting-edges A3.

C is a block of metal, which is secured to the upper face of the portionA2, extending transversely across the same immediately to the rear ofthe cutting-edges A3, where it serves as an anvil and guide for thetrimming-knife, as will presently appear.

rear arms of the semi-elliptical plates D above the 'upper edge of thehandle A. The opposite end of the handle is iiattened and curveddownwardly and provided with the verticallycutting edge E at rightangles to the body of the lever. 4

F F are steel arms pivotally connecting the downwardly-curved end B3 ofthe lever B with the lever E at a point adjacent to the operative end ofsaid lever. The handle A is adapted to move freely between the arms F,as will be readily understood.

G is a dat spring secured at one of its ends to the lower face of thehandle A, while its free end is adapted to bear upon the upper face ofthe handle B, as shown.

The pivots which retain the lever E in place are made removable, so thatthe said lever may be readily and easily removed when it may benecessary to sharpen the cutting-edge of the tool.

The Operation of the tool is simple, and from the foregoing descriptionwill be readily understood. The double-edgedtriangular eX- tension A2serves as a Very convenient tool for use in cleaning the hoof, and thesystem of leverage is such as to render `it possible to quickly and-accurately trim the hardest of hoofs with the exercise of but littlepower upon the handles A and B.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

1. The combination, with the handle B, of the lever pivotally connectedwith said handle and carrying a cutting-edge, and the handle A,independent of the lever and handle and carrying an anvil and guidedbetween the connections between the lever and the handle B,substantially as specied.

2. In a device for the purpose described, the combination, with thehandle B and the IOO lever E, of the arIns F F, pivotally connecting thelever and handle, the plates D, pivotally connecting the lever andhandle, and the handle A, Working between said arms and plates, and aspring between the handles, substantially as shown and described.

3. In a device for the purpose described, the combination, With thehandle B and the lever E, carrying a cutting-edge, of the parallel armspivotally connecting said handle and lever, the substantiallysemicircular plates D,

pivotally connected at one end to one end of i
